Frequently asked questions

Which Excel formats can I compare?

You can compare XLSX, XLSM, XLS, XLSB, SpreadsheetML XLS and CSV files. XLS and XLSB support values and formulas, but formatting differences are excluded.

Are comparison files uploaded to a server?

No. Reading, comparison and report generation happen in the current browser, and file contents are not sent to a server.

Can I compare multiple file pairs at once?

Yes. Each pair can use its own sheets and matching rules. Every successful pair gets a nine-sheet XLSX report, and two or more successful pairs also get a ZIP.
